Recommendation for Amps of Brunetti, ENGL, Hughes&Kettner, Mesa Boogie, Soldano etc. TAD has the remakes of the all times favorite 6L6 classics of RCA and GE. The TAD 6L6GC-STR is the perfect choice for the tone of the rock legends with powerful deep bass and clear but pleasing airy top end. The new 6L6GC-STR forwards the low end with pressure and has all the guts and bite to perfectly accomplish all the rocking sounds from R'n'R like SRV to modern NU-Metal. This TAD 6L6GC-STR combines the famous reliability of the american made Philips/Sylvania STR series plus the their beefed-up black-plate system like the highly regarded vintage RCA 6L6GC tubes. They joined the best of both worlds! Silky top end combined with deep bass response and lots of headroom make this tube a living classic. The TAD 6L6GC-STR and the TAD 6L6WGC-STR have our exclusive black-plate designs, gold gird wire, double getter construction, no-noise filaments and 1.2mm thick heavey duty glass envelope. Along with the TAD 6L6WGC-STR (GE-Style) this TAD 6L6GC-STR is our recommendation for excellent tone and maximum lifetime among the 6L6GC type tubes.
